This was approved by a board of naval officers, but never adopted and con- sequently he failed to realize any profit from its manufacture. Many models of other in- ventions were destroyed by a fire in the patent ofBce. He was among the first to employ adhesive plaster to make extension in case of fractured legs. At the time of his death, March 31, 1850, he had for some time confined his profes- sional labors exclusively to his duties at the Alms House, of which he was the physician. He was an active thinker on medical sub- jects even at that advanced age. In a dis- cussion on the relation of typhus and typhoid fever, he maintained their unity. Daniel Smith Lamb.

Maddin, Thomas La Fayette (1826-1908) Thomas La Fayette Maddin was born in Columbia, Tennessee, September 4, 1826, of Irish ancestry. His parents were the Rev. Thomas Maddin, D. D., and Sarah Moore. The son was educated in the common schools of Middle Tennessee and North Alabama and his medical education was gained under Dr. Jonathan McDonald, of Limestone County, Alabama, and he graduated from the medical department of the University of Louisville. Constant overwork in a large country prac- tice in Alabama proved a severe trial to a physical constitution never very rugged, and he went to Nashville, Tennessee. The oppor- tunities for medical observation offered him in Alabama were various and extensive, and a number of serious epidemics of typhoid fever gave him large experience in disease. In 1854 Dr. Maddin began private tuition in the various branches of medicine, and erected rooms for that purpose. For several years his classes were large, and his reputation as a teacher great. In 1857 Shelby Medical College was founded as the medical department of a projected university of the Methodist Episcopal Church South, which has since developed into the Vanderbilt Univer- sity. He occupied for two years the chair of anatomy there, and afterwards that of sur- gery. At the time of the War, Maddin was in charge of one of the largest of the hos- pitals established in Nashville by Confederate authorities. During the subsequent years of the War, the large number of wounded quar- tered in and near the city afforded Dr. Maddin an extensive surgical experience, and he per- formed a number of interesting operations, notably two for traumatic aneurysm. One of these required the ligature of the external iliac artery, the aneurysmal tumor extending from the inguinal region to a line drawn from the crest of the ilium to the umbilicus. The other was an aneurysm of the left subclavian artery, necessitating the ligature of that artery in its middle third and a number of subsidiary ves- sels. The delicate operation, which from its difficult and hazardous nature was declared inadmissible upon consultation with Dr. Frank H. Hamilton (q. v.), then medical inspector of the army of the Cumberland, was witnessed by that surgeon, who also gave his assistance. It was pronounced by him, resulting as it did in the relief of the formidable tumor, a great surgical triumph. In the circuit of his private surgical practice. Dr. Maddin is also credited with the first successful ovariotomy performed in Tennessee. In 1867 Dr. Maddin was called to the chair of institutes of medicine in the medical depart- ment of the University of Nashville, and after several years' acceptable service therein was transferred, about the time of the alli- ance of that institution with the medical de- partment of Vanderbilt University, to the chair 'of theory and practice of medicine and clinical medicine. Dr. Maddin was a member of the state med- ical society, the county and city medical societies, and contributed a number of able papers to their archives, and also to the med- ical journals of the time. For several years he was co-editor of the Monthly Record of Medicine and Surgery, published at Nashville. He died April 27, 1908, at his home, 109 Ninth Avenue South, Nashville, Tennessee. William D. Haggard. Magruder, Ernest Pendleton (1875-1915) Ernest Pendleton Magruder was born October 23, 1875, in Upper Marlboro, Mary- land, the son of Caleb C. Magruder, clerk of the Maryland Court of Appeals, and Eliza- beth Rice Nalle. After attendance at Marl- boro Academy and Georgetown (D. C.) Col- lege, he matriculated at Johns Hopkins Uni- versity, from which institution he graduated A. B. in 1895. Following several months of post-graduate study in chemistry and biology, he accepted the post of superintendent of schools in Williamsport, Maryland; later, on removing to Washington, he engaged in teach- ing special classes of prospective university matriculants. He graduated A. M. in 1900,
